Ayla Hines · Answer 1

Hash function is basically use to represent and index the actual value and key. It is one way operation in which the data is associate with the value and key in the function.

The main purpose of hash function is to maintain the integrity of the data. It basically consist two properties that are:

It is one way property hash function It has property of collision resistance

The main goal of hashing function is to convert the input of variable length into the field length which is known as hash value by using the cryptographic block.

Madden Hensley · Answer 2

Answer: Hashing function is the function that is concerned with the future use and thus is indexed in the database. This phenomena is done so that whenever the data that is related with the key can be retrieved and used whenever required.

Therefore, as it is a one-way mechanism, it makes it easy for the reviving data otherwise it would become difficult to search and extract the data from the huge hash tables.
